I cannot understand this obsession with excess heat as the sole criteria for the existence of the LENR reaction.
Transmutation of elements is undisputable proof of the existence of LENR. This transmutation can be determined with extreme accuracy if its preparation and evaluation are done with care. In many experiments done with spark discharge, exploding foils and other onetime short duration experimental events, excess heat cannot be detected but transmutation can and with great accuracy. Transmutation is the essence and crux of a nuclear event. Cold fusion apologists should switch their line of argument to transmutation from excess heat.
